Filed July 3,1, 19.614 ,Se,r,.,N0 .-1zs,2,s3 Claims. (Cl. 687-188) Thisinvention` relates to' skein dyeing machines.

In the art of dyeing yarns, the skeins are mounted on sticks which aresuspended within a vat and means is provided for cireulating the dyeingliquor' around, and through, the yarn. i n i In order to preventmarking, it is' necessary to minimize contact lbetween the skeins' andthe, skein-supporting stick andV it is also necessary thatv the skeinsbe spaced from each otherv orv arranged in' an operi pattern to permitfree flow of the liquor between and through the skeins and thus insureuniform results. l

It is therefore one object of the invention toy produce an improvedcarrier in which the Skcirsfare supported with minimum contact withtheir supports; in whichV the skeins are adequately spaced,.wherebyV theliquor circulates between' and' through, the skein'.

Loading" the' skeins onto the supporting sticks and placing thesticksdirectly in theV vat takes. time, during which the vat is idle. K

It is therefore afurther object of the invention to produce` an improvedcarrier which can be loaded and unloaded outside of the dye vat andwhich can be dropped into,A and lifted from, the vat quickly and easilyso as to reduce interruption of the operation to a minimum.

The full nature of the invention' willV be understood from the followingspecificationl aud-.accompanying drawings in which:

FIG. l2 is a vertical, sectional view looking in the direction of line12--12 on FIG. 10.

FIG. 13 is similar to FIG. 1l. but showing the yarncarrying sticks inanother position thereof.

A dyeing apparatus embodying the invention includes a vat 20 which isadapted to it in an emplacement 22 having a d-rain 24. The vat issupplied with water and chemicals through pipe 26 and is emptied throughdrain 28.

The vat is divi-ded by partition 30 into two compartments 32 and 34, thebottoms of which are formed by feicc screens 33 and 35, respectively.Below screens 33 and 35 isa heating coil 36 and an impellei" 38 which isdriven by pulley 40 which is driven by reversible motor M. When theimpeller is rotated in one direction, the dyeing liquor is circulated inthe direction of arrows 42, and vice versa. p

The yarn carrier is formed of two sections, A and B, which are adaptedto tit inY vat compartments 32 and 34, respectively. Carrier sections Aand B are formed of a common front wall 44, a common rear wall 45 andinner walls 46 and 47 which are spaced apart to form a channel 48 whichis adapted to receive partition 30` when the carriers are lowered in thevat, as shown in FIG. 4. The bottoms of sections A and B are open andtheir tops are formed of screens 5i) and 52. The opposite ends ofcarrier sections A and B are open and are provided with overheadsliding' doors 54.

Carrier sections A and B are integral with each other and with a cover56 which is provided with loop 58 for engagement with' hook 5 9 of alift', or overhead crane, not shown. By this arrangement, the' yarncarriers and the cover form a rigid assembly which can be lifted from,or lowered into, the vat as a unit. When the lcarrier sections are'lowered into the vat, their bottom edges come to rest onV flexiblegasket 59a to form a watertight seal. Also, when the parts are in thisposition, ang'e 60 `of the cover comes to rest on rim 61 to close' thetop of the vat. It will also be noted that the cover is raised abovescreens 50 and 52 and` is preferably domed so that, when it is in the`vat closing position of FIG. 4a passa-ge 62 is provided to permit liquorin one of the compartmentasucli' as compartment 32, to ilow upwardlythrough screens 33` and 50, then horizontally through passage 6.2, thendownwardly through screen 52vand 3,5' and' finally upwardly throughscreen 33 to complete the cycle, as indicated by arrows 42 in FIG. 4'.

In both embodiments, the skeins of yarn are supported on sticks whichhave only line contact with the skeins'. To this end, theskein-supporting sticks have a crosssection, ysuch as that shown in FIG.9, from which it will `be seen that upper divergent edges 64 support theskein and that they co-act with lower divergent edges 66 to keep theskein open to permit free circulation of the dyeing liquor around andthrough the skein, as shown by the arrows in FIG. 9.

Also in both embodiments, the sticks which support the yarn areautomatically uniformly spaced to provide clearance between adjacentskeins.

In one embodiment, the skeins are Suspended from the sticks 68, each ofwhich is provided with an enlarged head 70 which may be solid, or whichmay be in the form of a hollow frame as long as the width of the head,as viewed in FIG. 7; that is, the distance between sides 72 thereof isat least equal to the greatest width of the skeins supported by thesticks so that if the sticks are laid side by side, with the sides 72 oftheir respective heads touching, the skeins carried by radjacent stickswill be spaced as shown in FIG. 7.

When sticks 68 are used, the front and rear walls, 44 and 45, of thecompartments are provided with upper shelves 74 to receive the heads 70of the sticks from which the skeins are suspended. To load a carriersection, it is merely necessary to pla-ce the sticks, successively, onthe outer ends of the shelves and to push them inwardly, or in thedirection of arrows 78, until the head of the innermost sticks abuts theinner wall 46 or 47 of the compartment. See FIGS. l, 6, 7 and 8.

Instead of sticks 68, We may use sticks Si) which have the samecross-section as sticks 68, but which have flattened ends, as shown inFIGS. l0-13. When sticks 80 are used, shelves 74 and 76 are replaced byopenings 84 and 86 3,063,281l l i ,v I

FIG. 12 that openings 86 are deeper than openings 84 and that thedistance between wall 44 and 45 is greater than the length of sticks 80.In this construction, there is also provided a slide 88 which is movable`relative to wall 45 and has openings 90 which correspond to openings86. To insert sticks 80, slide 88 is moved until its openings 90register with openings 86. Sticks 80 are now inserted as far as theywill go through openings 86, as shown in solid lines at the top of FIG.12, and are then moved through openings 84 as far as they will go, asshown at the bottom of FIG. 12. With all of the sticks in their extremeright-hand position, lslide 88 is moved to bring solid portions 92thereof into registration with openings 86, thus locking stick 80against lateral movement.

The yarn tends to shrink and to control shrinkage, we provide lowershelves 76 for receiving sticks 68 or 80 which engage the lower ends ofthe skeins, as best shown in FIGS. 2 a-nd 3. It will be noted that thereare a number of vertically spaced upper and lower shelves 74 and 76 soas to accommodate skeins of various lengths and so as to provide for awide range of .shrinkage control. It will be noted that, once the doorsare closed, sticks 68, the outermost of which will abut the inside ofthe doors, will be locked against movement and that when sticks 80 areused, the outer ends of slides 88 will abut the inside of the door andwill be locked against any movement.
